Call Statistics Screen

You can access the Call Statistics screen on the phone to display counters, statistics, and voice-quality metrics of the most recent call.

Note You can also remotely view the call statistics information by using a web browser to access the Streaming Statistics web page. This web page contains additional RTCP statistics not available on the phone. For more information about remote monitoring, see Chapter 8, “Monitoring the Cisco Unified IP Phone Remotely.”

A single call can have multiple voice streams, but data is captured for only the last voice stream. A voice stream is a packet stream between two endpoints. If one endpoint is put on hold, the voice stream stops even though the call is still connected. When the call resumes, a new voice packet stream begins, and the new call data overwrites the former call data.

To display the Call Statistics screen for information about the latest voice stream, follow these steps:

Procedure

Step 1 Press the Applications button.

Step 2 Select Administrator Settings.

Step 3 Select Status.

Step 4 Select Call Statistics.

To exit the Call Statistics screen, press the Exit softkey.

The Call Statistics screen displays these items:
